1 results about "Metamaterial absorber" patented technology

The invention relates to an X-wave band meta-material absorber based on a dendritic structure. The meta-material absorber comprises a metal electric dendritic resonator, a medium base plate and a metal film. The characteristic of completely absorbing electromagnetic waves being vertically incident upon the surface of the meta-material can be realized by reasonably designing the geometry dimension and the lattice period of a metal dendritic unit. The meta-material absorber has the advantages of high absorption efficiency, simple structure, small volume, plane two-dimension omni-direction and the like. The absorber can be used as a high-efficiency electromagnetic heating device and can also be applied to electromagnetic wave collecting and detecting devices, such as radiant heat measuring devices.
